The basic mechanism of an air compressor is to convert power through sources such as electric motors and convert that power into pressurized air. A Freightliner air compressor is similar to an air brake compressor that sucks in outside air, compresses it, stores it, and produces energy. This is the most common issue people find with the Freightliner air compressor.
where is the air compressor on a freightliner Related Question:
Why is my Freightliner not building air pressure?
What Causes a Truck Not Building Pressure? When having a truck not building air pressure, it is usually because the unloader valve is stuck. However, if there’s a lot of pressure , and it still doesn’t kick the compressor, it means that you have a faulty air governor.
How much is an air compressor for a 2014 Freightliner Cascadia?

Where is the unloader valve on an air compressor?
Where Is the Unloader Valve Located? If you own a smaller reciprocating air compressor, you’ll likely find the unloader valve mounted on or inside the pressure switch. When the switch shuts the compressor off, it actuates the valve.
Why does my air dryer keeps purging?
When the air pressure becomes greater than that of the preset “cut-out”, the governor controls the unloader mechanism of the compressor to stop the compressor from building air and also causes the air dryer to purge.
How long should it take a semi to build air pressure?
Air pressure build-up from 85 psi to 100 psi should take 45 seconds or less. While driving, observe the air pressure gauge during build-up to ensure proper air system operation.
How do you unfreeze air brakes?
Brake pads can crack or fracture easily. Hammer on the top and bottom of the drum and then get back into the cab and try to rock the truck back and forth. You can also cut the air supply and resupply the trailer with air a couple of times to use the pressure to break the ice. Repeat until the brake releases.
What happens when AC compressor goes bad?
When your ac compressor fails, less air will come out from the vents, the air coming out could be warm, and the system may continually run without actually cooling your home. This is because refrigerant isn’t pumped through the system, and it can result in a higher power bill.

How do you know if your unloader valve is bad?
Water leaks and inconsistent behavior are also signs of a potential failure in the near future. González: The typical signal when there is an unloader malfunction is a reduction of flow through the nozzle, which results in pressure loss. Dean: Typical symptom of an unloader failure is a sudden smooth pressure loss.
What is an air compressor unloader?
An air compressor unloader valve is a device used by air compressors to release the trapped air inside the compression chamber and tank discharge line when the motor stops. This allows the motor to start up easier.
What is an unloader?
The unloader diverts the flow of water from the outlet side of the pump back to the inlet side, causing water to flow in a loop back to the pump under virtually no pressure rather than to the nozzle under operating pressure. Flow may be directed back to the pump inlet or to a float tank or other type of reservoir.
